4.0 out of 5 starsHands show up at night on mine
Like the watch, attached a pic where you can see the hands in the dark.. maybe this is an improvement they made in response to other complaints.Just a heads up if you have larger wrists the bands are going to be tight. Barely got the silicone band on the last hole, I cannot clasp the metal band after adding the extension links, going to need to contact them for another extension.My wrist is approx 9.25' around where they recommend placing the watch... for reference.Hope this helps!

The best traditional / connected marriage
This watch has all the features I was looking for: autonomy, sensors, resistance to seawater and a stylish and sporty look. It looks more like a classic watch, which I prefer over watches with just a completely black screen...

Excellent watch
They really bring together the best of two worlds, the technology of a smartwatch with the aesthetics of a classic watch. The materials are spectacular and the measurements are quite accurate. The best thing is that it looks really good!! It really met all my expectations.

I wanted to love everything about it
When I first open the box and used it for 2 days I loved it. It was everything I wanted, Fitness, steps, heart, sleep, and a classy business watch. Then I noticed it consistently failed to track sleep, it consistently miscalculated steps. These were basic things my Apple watch had just done that I took for granted. Then about a week in I started struggling with minute hands only moving forwards and not backward. This was significant in that the hands move both ways to get out of view of the small display. When they cant move backward the time is always wrong. I called support, we reset, we repowered etc. They wouldn't send a replacement because I got it from Amazon so then it was send it back, get your $500 back and start looking for a real replacement. I am extremely disappointed because Withings is unique in this space, it looks so great and well made, it just doesn't work and isn't reliable. I thought about trying it again but saw many forums with the same experiences. Theirs died 2 years in. I wasn't risking it for a bigger ticket item such as this. I will just have to fall back to apple again.

Extensive and fairly easy to use
I got a watch like this watch due to a recommendation from my cardiologist. I have found this watch to be easy to use and to understand its information. It seems very comprehensive and the data is easy to read on the smart phone app. I previously had a Garmin and it was impossible to pair to my phone, impossible to operate, and was much less thorough. To be fair, it was also much less expensive. This watch has all the features my cardiologist recommended. I set up a walk activity today and failed to end the activity, so my watch thinks I went on a 5 hour hike today. So there’s that sort of operator error to deal with. I also have to initiate items such as blood oxygen saturation assessment and ecg test, so the data gathering isn’t automated. Still, I think this watch is very useful. The long battery life is also very useful.The medical features work better with the plastic band rather than the classy SS band. For tests you can push the face of the watch against your arm, but activities won’t record well with that band.It was noticeably heavy when I first put it on, but I got used to it quickly. If you’re looking for a good medical watch, I can definitely recommend this watch and at $500 it is less expensive than my cardiologist thought a watch with these features would cost.

Proud to wear it.
Convinced me I no longer need a luxury watch. Feels premium, and has the health benefits of a smartwatch. I like to track my steps and heart rate throughout my day. Also ensures I never miss a call which I tend to do without. I do have an issue that my watch minute hands do not line up perfectly. But that’s a nitpick.

It looks like a watch
I have atrial fibrillation treated via catheter ablation that occasional goes awol. I was looking for a wearable device that will track my AF, and enable me to record an ECG of any AF events for my heart specialist. The Withings Scanwatch Horizon goes beyond what I was looking for but in the end, it just looks like a watch! Battery life is way off the scale when you compare it to other similar devices on the market. Paired with the Health Mate app it gives me precise details on whats going on with my general health so I can evaluate my heart health and possibly tweak my lifestyle here and there and keep my AF at a controllable level.

Love the watch, wish the hands were brighter in the dark
All in all this watch is exactly what I was looking for in a hybrid watch.It functions exactly as it was described and checks all my boxes for what I was looking for, especially the amazing battery life.I did not give this watch a 5 star rating due to the dimness of the hands.Being a dive watch, I would expect these to be much brighter, especially compared to other dive watches I have.I reached out to the company to ask if this is something they would improve for me but they will not and they do not have a repair department.I will be looking for other watch repair shops that will do this work.Other than this opinion, I enjoy the watch very much and wear it everyday.

' Rolls Royce of Smart Watches '
This watch is absolutely gorgeous, I bought the Green face because of my Astrological sign. The features are great, I am better able to keep track of my step count, sleep and SP 02. The battery life is great, 30 days and still at 10%. Because I live in Canada the ECG function does not work, bummer, hoping Withings has applied to Health Canada for its approval. Would be nice, and yes I too would like to see a Weather application in an update, can't be that difficult. Other than that, I would recommend this watch to anyone interested in monitoring their overall health.

2 Months Ownership, Great Watch
I love this watch.I agree with all the highly rated reviews.I needed a smart watch to help me monitor my afib.This fills the bill and is very accurate. It's very stylish and feels good on the wrist.The battery has lasted 30 days on a charge as advertised.My only complaint is that it's a pain in the neck to charge.The magnetic connection is very weak.When you try to connect it its very touchy and has to be exactly right.When you remove your hand it frequently disconnects and it's hard to know if it's even charging. It's a game of trial and error.

A great watch that tracks your day

Massive
I want to begin with that the watch is superbly manufactured, It doesn’t feel cheaply made. I was also impressed that you include the tools required to remove and add bracelet links, and that you provided an additional flexible band. The watch performs as expected, and I am quite pleased with how easy it is to change its settings. I must add that I really wanted to like this watch. There is however another side to my thoughts.The watch is huge. It is much larger and heavier than my other watches. The Horizon’s weight becomes more apparent when the stainless-steel bracelet is used. While the watch face is very readable the round led display feels like a rather large black hole in the upper center of the watch. This makes the watch somewhat unattractive. By the way, when the display is displaying information, the watch becomes more appealing. I’ll now address my thoughts regarding the charging connector.I found that the magnetic connection is not as strong as my Apple watch. As a matter of fact, the Horizon’s connector is more difficult to connect because there are several pins that need to be aligned. With a weaker magnetic connection, it becomes difficult to maintain that connection with the pins. This becomes more apparent when the watch is attached to the stainless-steel bracelet. Unless the bracelet is disconnected from the watch, it is difficult to connect the watch to the charger.Unfortunately, although I really wanted to like this watch, I felt compelled to return it. I hope that you have a different experience and choose to buy and keep this well-made watch.

My Favorite Smartwatch
I've tried so many 'Smart' or digital tracking watches over the years and so far this has been my favorite by far.Every watch I've tried has ended with the same pitfalls, battery life and longevity.The Moto 360 was a great watch, but after 2 years I couldn't get it to retain a charge, and replacing the battery on those for even the most average user was an exercise in futility.The Fitbits worked really well, it had the functionality I needed, and the battery would last most of a week, but a little more than a year after purchasing it (and just out of warranty), the screen started glitching out, it would register phantom inputs, and the battery would die within 24 hours.So far this Withings watch has been top notch on everything.I can see messages from my phone at a glance, it tracks all of the health goals and statistics I need and more, and the battery lasts FOREVER.I literally only charge this thing once every 3 weeks, and with the warranty they offer through the manufacturer (5 years), I don't think I'll be worrying about this dying on me in the time frame that I've found problematic in the past.This IS the most expensive version of this watch, I chose this one because I really liked the look.It wears, feels, and looks like a quality traditional watch, and I've found it completely worth the price so far.You can though get the same functionality from one of the cheaper versions.If you are looking for a great health tracking watch, and you don't need all of the touchscreen app functionality from other 'smart' watches, this is truly the way to go.

Classy timepiece with hidden modern ingenuity
Withings knocked it out of the park. Great watch. Battery life does well. Gives me the options I'm interested in and looks great all the time. Stellar job on this fine piece of engineering. A lot of other watch companies could learn a few things in being classy, modern, and durable.

Best compromise there is
No doubt about it the watch is beautiful. I got tired of reminders, notifications, and taps from my smartwatches. To be honest they're fun for a bit but annoying after a week as I have my phone to hand most of the time and get enough notifications there along with my 80+ Slack messages a day.I wanted sleep tracking and workout information without overload. This gives me enough info when I want it (the companion app is excellent) without pulling me away from what I'm doing. While I'm not sure I get the accuracy I did with Apple Watch or Whoop bands I have a comparison of trends which is fine by me. I'm not a pro athlete but I work out 4-5 times a week so I like to have a guage.Scanwatch does exactly this. It's excellent at giving me what I want when I need it. I believe the workout data is off - compared to other trackers it registers lower BPM and calories burned BUT I can see a trend.
August 23, 2022 | anonymous
Beatiful but cant keep the time.
Very satisfied with the look, feel and functionality, but having to re-adjust the time or open the app to syn the correct time each few days, you don't expect this kind of issues from a $510 watch.

Step counter
I like everything about this watch except for one thing and I think it is a big thing . The step counter is way off not even close to the steps I walk. It is about 1/3 of the steps I get on my google Health and fitbit. Overall the other sleep, heart rate and all are very good.

A great hybrid watch - analog face with digital fitness/sleep analysis
Had first 4 Apple watches and finally ditched them when the screen cracked and they wanted $395 to repair. Didn’t wear a watch for awhile and didn’t miss it. Then I got a free Fitbit Inspire and enjoyed having the fitness and sleep tracker, but found that it could be very inaccurate on fitness. So I researched and came across the Scan Watch. Bought the Horizon model as it is beefier and looks sporty.Things I really like:1. Design2. Battery life3. Fitness tracking (I play tennis, workout, cycling and weights.4. Sleep tracker is good but maybe the Fitbit is better? Not sure yet.5. The ECG and SpO26. The built in alarm, timer, stop watch.7. Software is very good and has a lot of relevant data.8. Feels solid on the wrist and not a bother sleeping with it9. East to use crown button to navigate menus10. Had notification features that ties into other apps - I don’t need generally but some may find useful.11. Accuracy seems quite good12. No subscription feesAll in all, I am extremely pleased and found no real dislikes. If you want a nicelooking analog watch with good fitness/sleep tracking, you can’t go wrong. I think they did a fantastic job with their hybrid watch!

Beautiful Watch But...
Yes, it is a very nice looking dive watch BUT I am not comfortable with the results I am getting. The step counter is far off, the Android App is not easy to use and there is no operation manual per se! I still don't know what the dial at six o'clock is used for after a weeks use. Sorry, I don't recommend spending the $500 (US) for it!!!

Sick of an ugly Apple Watch? This could do it
First let me say that I’m a woman who is 5’4”, 125 lbs and small boned. I was afraid this wouldn’t fit my wrist but it does. This was tough to figure out because every amazon or external review was written by a man. I have to point this out because it BARELY fits and I haven’t tried adjusting the metal band yet. With that said it looks like a normal watch that I wouldn’t be ashamed to wear outside the gym or my Silicon Valley office. Yes, it has less features than my 4th Apple Watch but aside from the find my phone feature I’m not sure I’ll care.So yes women, someday tech companies will figure out we’ll drop $$$. Until then, this may be the best option.

Great watch! Battery myth...
The best looking, excellent build quality, thoughtful app. Notification is done nicely.Battery Myth:My first green horizon watch battery is verybad the battery dropped 14% on day one. I tried Amazfit, and it only drops 5% a day. I tried to disable a lot of things and it became about 7-8% a day.Second Blue horizon, more than 24 hours later, it still shows 100%. I could not believe it. Almost like I complained and they did something remotely and manipulated the battery meter... 😊Sleep Track is nice and main reason I bought it.
